Twenty-nine participants were observed and interviewed over the twelve class days in which they were engaged in Alien Rescue. Students'…

The growing interest in the field of educational technology in the design of constructivist learning environments has led to a renewed examination of problem-based learning (PBL), an approach to instruction in which all learning results from students' efforts to solve a complex problem. Concurrent advances in technology make it possible to use…

Examine students' motivational orientation (intrinsic/extrinsic) during problem-based learning (PBL), comparing it to their orientation during typical class activities. Participants were regular education students who used "Alien Rescue," a computer-based PBL program designed for sixth grade science. Implications of the findings for…
